Why the study?
Electroanatomic mapping-guided CRT-D implantation has been developed to address issues of standard techniques, but had not been previously described in congenital heart disease.
This case report describes the use of electroanatomic mapping to guide CRT-D implantation in an adult patient with congenital heart disease, potentially reducing x-ray exposure and contrast use.
No takes yet. Share an insight, caveat, or question.
May reduce fluoroscopy in complex CHD implants; leaves open prospective validation before wider use.
Ciriello et al. (2022) studied this question.
